Title:
  libvirt overwrites externally set vlan tags in macvtap passthrough
  mode with VFs

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) newton series:

Bug description:
  Starting from version 1.3.5, Libvirt allows to set a vlan tag for macvtap 
  passthrough mode on SR-IOV VFs. Libvirt also removes any vlan tags that 
  has been set externally, by the ip link command.
  Due to this, it's not possible to set a vlan for VFs with macvtap.
